Its my first experience to learn about device drivers in Linux.
so here i come to know about USB drivers. when i was reading about drivers at that time i realize that there are different types of drivers like character device driver and block device drivers. So my concern was with USB driver. For USB connectivity I was looking for an Application in C language which will run at boot time of Alexa device. So here i have learned and search about libusb. Libusb is a library which have different APIs and useful for transfer data through USB. This library can make Bulk transfer, Control transfer, Interrupt transfer and can also make Isochronous transfer.
